the university students will respond to CVS-F3 survey form and then they will be subjected to complete ophthalmic examination and investigations
CVS-F3 is a survey form consisted of up to 30 questions regarding Computer Vision Syndrome (CVS) complains, thereafter a randomized sample of students will be subjected to complete ophthalmic examination including visual acuity and refractive measurements, intraocular pressure measurements, Slitlamp and fungus examinations, mfERG examinations. the sudents will be requested to decrease their screen time and the examinations will be repeated one month later.
9,217 studies on the registry are indexed under Syndrome; 1,031 are open to participants now.
This study's enrollment of 733 is above the median of 50 across 6,515 interventional studies indexed under Syndrome.

Exclusion Criteria:
the students in this group are not complaining of CVS symptoms but will be examined to diagnose CVS or exclude it
Diagnostic Test: mfERG (multifocal-retinogram)
the students in this group are complaining of CVS symptoms but will be examined to document their complains and correlate to clinical findings
Diagnostic Test: mfERG (multifocal-retinogram)
mfERG will be performed for the students to document the effect of CVS on retina
visual acuity
visual changes i.e. uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) using logMAR measurements following reduction of screen time
Time frame: 1 month
near vision
near vision changes following reduction of screen hours using card test, near visual acuity chart and near point test while the measurements will be diopters and lines of near chart
